| Title | Pidgin などの製品で使用される libpurple におけるサービス運用妨害 (クラッシュ) の脆弱性 |
|---|---|
| Summary | Pidgin などの製品で使用される libpurple の SILC プロトコル plug-in 内にある g_markup_escape_text 関数には、glib2 の特定バージョンとの相互作用に関する処理に不備があるため、サービス運用妨害 (クラッシュ) 状態となる脆弱性が存在します。 |
| Possible impacts | 第三者により、不正なポインタの使用と out-of-bounds read を誘発する不正な UTF-8 シーケンスを介して、サービス運用妨害 (クラッシュ) 状態にされる可能性があります。 |
| Solution | ベンダより正式な対策が公開されています。ベンダ情報を参照して適切な対策を実施してください。 |

| Summary | The g_markup_escape_text function in the SILC protocol plug-in in libpurple 2.10.0 and earlier, as used in Pidgin and possibly other products, allows remote attackers to cause a denial of service (crash) via invalid UTF-8 sequences that trigger use of invalid pointers and an out-of-bounds read, related to interactions with certain versions of glib2. |
